11 Dedicated XCC management connector (1 Gb RJ45)

  • Dedicated XCC management connector (1 Gb RJ45) activity LED (green): Use this green LED to distinguish the network status.

    • Off: The node is disconnected from a LAN.

    • Blinking: The network is connected and active.

  • Dedicated XCC management connector (1 Gb RJ45) link LED (green): Use this green LED to distinguish the network status.

    • Off: The network link is disconnected.

    • On: The network link is established.

Note

  • It is recommended to use SMM3 Ethernet port as the default dedicated management network. If required to use node front Ethernet port as dedicated management network, refer to XCC user guide for network configuration instructions.

12 Identification LED (Blue)
  • Use this blue LED to visually locate the node among other nodes. This LED is also used as a presence detection button. You can use Lenovo XClarity Administrator to light this LED remotely.
13 Check log LED (Yellow)
  • When this yellow LED is lit, it indicates that a system error has occurred. Check the XCC event log for additional information.

14 RoT LED (Yellow)

15 USB 2.0 / USB 3.0 / DisplayPort Alternate Mode Type-C connector
  • This connector supports only a cable or a device with DisplayPort Alternate Mode functionality.
16 25 Gb SFP 28 Port 1 link and activity LED (green) Use this green LED to distinguish the network status.
  • Off: The network is disconnected.
  • Blinking: The network is accessing.
  • On: The network is established.

17 25 Gb SFP 28 Ethernet port–Port 1 (Share-NIC).

18 25 Gb SFP 28 Ethernet port–Port 2

19 25 Gb SFP 28 Port 2 link and activity LED (green). Use this green LED to distinguish the network status.
  • Off: The network is disconnected.
  • Blinking: The network is accessing.
  • On: The network is established.

20 External diagnostic handset connector

21 Power button with LED (Green). Press this button to turn the node on and off manually. The states of the power LED are as follows
  • Off: Power is not present or the Power Conversion Station, or the LED itself has failed.
  • Flashing rapidly (4 times per second): The node is turned off and is not ready to be turned on. The power button is disabled. This will last approximately 5 to 10 seconds.
  • Flashing slowly (once per second): The node is turned off and is ready to be turned on. You can press the power button to turn on the node.
  • On: The node is turned on.
